Located at 12,836 feet above sea level, this national natural landmark shows the alpine tundra landscape wonderfully. At this high altitude, there are no trees because of the excessive cold, wind and adverse soils.

The natural landmark is situated within the Summit Lake Park, which is managed by the city of Denver, as part of their Denver Mountain Parks division. Rare alpine and arctic plants inhabit the area, some species of which only occur here and the Arctic Circle. The difference between alpine and arctic tundra, is that arctic tundra has permafrost, therefore alpine soils are usually better drained.

Summit Lake is the source of Bear Creek, which flows through the Mt Evans Wilderness. This vast national wilderness area surrounds the area, which borders the Arapaho National Forest and Mt Evans SWA.
